Currently, rustc uses a heuristic to determine if a range expression is not a literal based on whether the expression looks like a function call or struct initialization. This fails for range literals whose lower/upper bounds are the results of function calls. A possibly-better heuristic is to check if the expression contains `..`, required in range literals. Of course, this is also not perfect; for example, if the range expression is a struct which includes some text with `..` this will fail, but in general I believe it is a better heuristic. A better alternative altogether is to add the `QPath::LangItem` enum variant suggested in rust-lang#60607. I would be happy to do this as a precursor to this patch if someone is able to provide general suggestions on how usages of `QPath` need to be changed later in the compiler with the `LangItem` variant. Closes rust-lang#73553
In the following example, an inaccessible path is suggested via
`use foo::bar::X;` whereas an accessible public exported path can
be suggested instead.
```
mod foo {
mod bar {
pub struct X;
}
pub use self::bar::X;
}
fn main() { X; }
```
This fixes the issue.

Add re-exports to use suggestions
In the following example, an inaccessible path is suggested via `use foo::bar::X;` whereas an accessible public exported path can be suggested instead.
```rust
mod foo {
mod bar {
pub struct X;
}
pub use self::bar::X;
}
fn main() { X; }
```
